I have often been vexed by textbooks or professors offering one word proofs to quickly justify concepts that do not come so lazily to me. (That's a pangram!) The purpose of this talk will be to shed some light on some of these one word proofs, by giving an introduction to categories. This talk will be accessible to anyone who has ever been similarly frustrated (so all of us), as my examples include things such as the integers, partially ordered sets, and matrices. On the other hand, as a warning, if you can define a natural transformation without looking it up, then this talk will probably be boring for you.
